关于jbpm的文档
一个引擎多个service：
RepositoryService repositoryService = processEngine .getRepositoryService(); //部署服务器 ExecutionService executionService = processEngine .getExecutionService(); //执行服务器 TaskService taskService = processEngine .getTaskService(); //任务服务器 HistoryService historyService = processEngine .getHistoryService(); //历史服务器 ManagementService managementService = processEngine .getManagementService(); //管理服务器 各个Service的作用： RepositoryService 管理部署对象和流程定义 ExecutionService 管理执行的，包括启动、推进、删除Execution等操作 TaskService 管理任务的 HistoryService 历史管理（执行完的数据管理，主要是查询） IdentityService jBPM的用户、组管理 ManagementService
